BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to an exercise device, and moreparticularly to an exercise device comprising an adjustable frame, inwhich a distance between a seat frame and a handle frame can be freelyand conveniently adjusted.

2. Description of Related Arts

As shown in FIG. 1 of the drawings, a conventional exercise device, suchas a conventional stationary exercise bicycle disclosed in U.S. Pat. No.6,155,958 to Goldberg, comprises a frame having a front and a rearsockets, an adjustable seat, mounted in the rear socket, and a handlebarmounted in the front socket. In this conventional exercise device, theadjustable seat is extendable in fore and aft direction relative to therear socket.

More specifically, the frame disclosed in '958 patent comprises a seatholding mechanism which is capable of mounting the seat assembly atdifferent positions relative to the frame. Moreover, the seat isadjustable for height and connected to the seat socket. The seat postpop pin permits height adjustment of the seat. The fore and aft saddlepop pin permits adjustment of the seat by sliding fore and aft in theseat socket. Thus, it can be seen that the seat is movable relative tothe seat socket.

A major disadvantage of this configuration of the stationary exercisebicycle is that the connection between the seat socket and the seat isvery easy to break because the connection is relatively weak while theseat is subject to heavy weight of a user. When the connection betweenthe seat socket and the seat fails, it may cause harm to the riderbecause the rider may accidentally falls from the stationary exercisebicycle.

Furthermore, the handlebar of the stationary exercise bicycle comprisesan upright portion lateral bar and a second bar extended forwardly fromthe lateral bar in one common plane. These can easily be observed fromFIG. 1. One major disadvantage of this second bar is that the user isnot guided to grip on suitable positions of the handlebar. Since thesecond bar is a one-piece member, the user may grip on any position ofthe second bar. As such, the resulting riding posture may not becorrect. When the riding posture is incorrect, the user may be hurt byhis or her own riding habit. The conventional stationary exercisebicycle is not capable of remedying this situation or alleviating thispotential danger.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 2 to FIG. 3 of the drawings, an exercise device, suchas a stationary bicycle frame, according to a preferred embodiment ofthe present invention is illustrated, in which the exercise devicecomprises an adjustable frame 10 and an exercise equipment 20 supportedby the adjustable frame 10. The adjustable frame 10 comprises a mainsupporting frame 30, a handle frame 40 and an adjustable seat assembly50.

The main supporting frame 30 comprises a frame member 31 forfacilitating a predetermined exercise type, such as bicycle exercise,wherein the frame member 31 has a first end portion 311 and a second endportion 312.

The handle frame 40 is supported by main supporting frame 30 at aposition above the first end portion 311 of the frame member 31, andcomprises a first handle bar 41 and a plurality of second handle bars42. The first handle bar 41 has a transverse portion 411 and twolongitudinal portions 412 extended from two ends of the transverseportion 411 for a user's hands to grip thereon respectively so as toallow the user to selectively exercise in a first riding posture.

On the other hand, the second handle bars 42 are extended from the firsthandle bar 41 for the user's hand to grip thereon respectively so as toallow the user to selectively exercise in a second riding posture.

The adjustable seat assembly 50 is adjustably supported by the mainsupporting frame 30 at a position above the second end portion 312 ofthe frame member 31, and comprises a seat frame 51 and a seat member 52.

The seat frame 51 has a coupling portion 511 moveably coupled with themain supporting frame 30. On the other hand, the seat member 52 ismounted on a support portion 512 of the seat frame 51, wherein byadjustably and movably coupling the seat frame 51 with respect to themain supporting frame 30, a distance between the seat member 52 and thehandle frame 40 is capable of being freely adjusted for fittingdifferent users with different riding postures.

According to the preferred embodiment of the present invention, theexercise device is preferably embodied as a stationary bicycle, so thatthe adjustable frame 10 is embodied as a stationary bicycle frame. Thus,the exercise equipment 20 comprise a bicycle wheel 21 rotatably mountedon the first end portion 311 of the frame member 31, a plurality ofpedals 22 operatively provided on the second end portion 312 of theframe member 31, and a driving mechanism 23 supported by the framemember 31 for transmitting the movement of pedals 32 into the rotationof the bicycle wheel 21.

As shown in FIG. 2 of the drawings, the frame member 31 of the mainsupporting frame 30 is substantially elongated in structure wherein thefirst end portion 311 and the second end portion 312 constitute frontand rear end portions of the frame member 31 respectively. The mainsupporting frame 30 further comprises a plurality of leg frames 32supporting the frame member 31 and the exercise equipment 20 on a groundsurface. Of course, the leg frames 32 also serve to support the handleframe 40 and the adjustable seat assembly 50 at a predeterminedelevation above the ground surface.

On the other hand, the handle frame 40 further comprises a supportingmember 43 extended from the frame member 31 of the main supporting frame30 to suspendedly support the first handle bar 41 and the second handlebars 42 at a predetermined elevation above the ground surface. Thetransverse portion 411 and the longitudinal portions 412 of the firsthandle bar 41 constitute a substantially U-shaped cross sectional shapethereof to define a handle cavity 413 between the transverse portion 411and the longitudinal portions 412, wherein a user is arranged to grip onthe two longitudinal portions 412 while seating on the seat member 52,wherein the user's legs are arranged to step on the pedals 22 of theexercise equipment 20 for exercising at the first riding posture.

Each of the second handle bars 42 is also inwardly extended from thelongitudinal portion 411 of the first handle bar 41 in the handle cavity413. It is worth mentioning that each of the second handle bars 42 alsohas a predetermined cross sectional shape designed to allow the user togrip on the second handle bars 42 for riding on the exercise device at asecond riding posture.

At this point, it is important to mention that since there are twosecond handle bars 42, each of the second handle bars 42 substantiallyguide the corresponding user's hand to grip thereon. The result is thatthe user is prevented from gripping on incorrect positions on the secondhandle bars 42, and this feature ensures that the second riding postureis correctly made by the user.

The frame member 31 of the main supporting frame 30 further has anelongated coupling slot 313 formed at a second end portion 312, whereinthe coupling portion 511 of the seat frame 51 is adjustably insertedinto the elongated coupling slot 313 so as to adjustably couple the seatframe 51 to the main supporting frame 30. More specifically, thecoupling portion 511 and the support portion 512 of the seat frame 51are extended at a predetermined angle of inclination in which thesupport portion 512 is upwardly extended to support the seat member 52,while the coupling portion 511 is longitudinally extended (with respectto the frame member 31) from a lower end of the support portion 512 toadjustably insert into the elongated coupling slot 313.

Thus, the adjustable seat assembly 50 further comprises a securinglocker 53 provided on the second end portion 312 of the frame member 31,and is arranged to penetrate the second end portion 312 to lock up aposition of the coupling portion 511 of the seat frame 51.
